Seems like they claim that they base the data processing on:
1. contract about delivering services between you and them
2. profiling is based on a legitimate interest of their administration
3. sending data to third parties based on consent
The way they write it I would call "Polish legalese", so I'm quite confident it was written very carefully by a lawyer and they know it is sketchy.
BTW I really recommend reading "Guidelines on Consent under [GDPR]" by Article 29 Working Pary, an EU body established by the previous directive. It's written in simple language with examples of what is valid consent. And how regulators think about it.
